FROZEN CONFECTIONERY PRODUCT WITH A NATURAL STABILISER

Description

Field of invention

[0001] The present invention relates to a frozen confectionary product comprising a natural stabiliser composition. The present invention also relates to a method of manufacture for the frozen confectionary product.

Background of the invention

[0002] Stabiliser compositions are used in frozen confectionery products to improve and/or maintain certain characteristics of the products. These characteristics can be the texture, scoopability, melting rate, heat shock resistance and shelf life of the frozen confectionary products.

[0003] Efficient stabiliser compositions well known and widely used in any range of frozen confectionary products include ingredients, in particular emulsifiers, defined as "additives" or ingredients with so-called "E-numbers".

[0004] Examples of such additives often found in frozen confectionery formulations include mono- and diglycerides of fatty acids, esters of mono- and digylcerides of fatty acids, polyglycerol esters of fatty acids, polysorbates etc. They have certain drawbacks. These emulsifiers are in fact perceived as "non-natural" ingredients, deemed to be unhealthy in the eyes of the consumer. The presence of these ingredients in frozen confection recipes leads to reduced authenticity of the frozen confectionary products. There is therefore a need to provide frozen confectionary products that are made from natural ingredients.

[0005] Natural emulsifiers are known but they are often costly and complex materials that are difficult to obtain and manufacture. They are not as efficient as any known additives to stabilize frozen confections and their use is therefore limited.

[0006] So-called "Premium" ice creams made with natural ingredients in particular natural emulsifiers such as egg yolk are known. Such "premium" range of frozen confectioneries is usually characterised by products with a rather low overrun e.g. below 50%, high levels of fat and high levels of protein. Their total solid content is also usually above 40wt%. The low overrun in these products provides them with a low thermal conductivity and therefore these products are less affected by heat shock. On the other hand, the high protein content usually compensates for the need of any "non natural" emulsifier. However the proteins being expensive, this solution is not suitable for standard or "mainstream" frozen confectionary products.

[0007] Mainstream frozen confectionary products are usually characterised by an overrun above 80% and their content in protein is lower than that of "premium" frozen confectioneries, to make such products affordable to most consumers.

[0008] Providing mainstream frozen confectionary products using natural ingredients is a challenge. Premium ice creams are usually made with fat from a dairy source and contain little or no fat from a vegetable source. These frozen confectionary products are expensive to manufacture and thus costly to the consumer due to the high load of quality ingredients. These products can also be seen as unhealthy due to the high levels of fat and sugars.

[0009] There is a need to provide mainstream frozen confectionary products that are healthier, smoother, stable, scoopable with relatively lower total solids, which are made with natural ingredients and which are cheaper to manufacture.
There is an inherent need to provide mainstream frozen confectionary products and stabiliser compositions that address the aforementioned problems.

[0010] EP2119370 discloses an aerated frozen confectionery product comprising fat, protein, sugars and a stabiliser composition comprising egg yolk, at least one acidifier and at least a natural gum.
WO 98/09536 by the Applicant Unilever PLC is titled "Frozen aerated product ice cream free of emulsifier and preparation thereof". The WO 98/09536 publication discloses frozen aerated products with: i) 1-6% fat, ii) 0% emulsifier and iii) 0-1.0% stabilizer such as natural gums. The WO 98/09556 publication fails to disclose any overrun values.
WO 98/09534 by the Applicant Unilever PLC is titled "Frozen aerated product ice cream free of emulsifier and preparation thereof". WO 98/09354 publication discloses frozen aerated products with: i) 6-18% fat, ii) 0% emulsifier and iii) 0-1.0% stabilizer such as natural gums. WO 98/09534 publication fails to disclose any overrun values.
EP 1400176 by the Applicant Unilever PLC is titled "Frozen aerated products". EP 1400176 publication discloses frozen aerated products with a large overrun range of between 10%-250%. The frozen aerated products of EP 1400176 publication do not require any stabilisers or emulsifiers.

[0011] cream that contains polyunsaturated fats. US 2006/0233919 publication fails to disclose a frozen confectionary product with an overrun and a stabiliser composition according to the present invention.

[0012] EP 2025240 by the Applicant Nestec SA is titled "Natural stabiliser system for a desert". EP 2025240 publication discloses a stabiliser system that can be used in the manufacture of natural frozen confectionary products. The stabiliser system of EP 2025240 comprises native rice starch and fibres from vegetables, fruits or mixtures thereof. Starch is a carbohydrate and the use of starch is a non traditional component of frozen confectionary products. EP 2025240 publication discloses frozen confectionary products which are aerated with an overrun of 20-80%. EP 2025240 publication fails to disclose a natural gum or at least mixtures of different natural gums in the stabiliser system.

[0013] There is thus a need to overcome the deficiencies as known in the prior art.

Summary of invention

[0014] In the context of the invention, "natural" or "clean" is used to designate ingredients that are consumer friendly, ingredients that consumers perceive to fit with ice cream essence/nature and authenticity. As an example, although mono- and diglycerides could be found in nature, they are not considered as "natural" ingredients in the context of the invention.

[0015] In a first aspect, the present invention relates to a frozen confectionary product comprising 3% to 12%, preferably 4% to 12%, most preferably 4.4% to 10% fat, 2% to 2.7% protein, most preferably 2.4% to 2.7% protein, up to 29%, preferably 0% to 26%, most preferably 12% to 26% sugars, 31% to 45%, preferably 34% to 40%, most preferably 36% to 39% total solids, all of these % values being weight%. Furthermore the frozen confectionary product comprises a stabiliser composition. The stabiliser composition comprises at least one acidifier and 0.7% to 1.6 % egg yolk, up to 10% of the at least one acidifier; and 0.01% to 0.4% of at least one natural gum and wherein the frozen confectionary product has an overrun of at least 80%, preferably between 80% to 210%, more preferably between 90% to 160%, most preferably between 100% to 150%, and having a pH value of 5.6 to 6.5.

[0029] The egg yolk can be in the form of an egg yolk powder or liquid egg yolk.

[0030] In a further aspect the egg yolk can be sugared.

[0031] It is to be appreciated that more than one natural gum can be used and more than one acidifier can be used in the stabiliser composition.

[0032] Natural gums obtained from seaweed and used in the present invention include agar, alginic acid, gellan and sodium alginate. It should be noted that the natural gum obtained from seaweed, carrageenan is not used in the present invention.

[0033] Natural gums obtained from non-marine botanical resources and used in the present invention include gum arabic, gum ghatti, gum tragacanth, guar gum, locust bean gum, betaglucan, dammar gum,inulin, glucomannan,mastic gum, psyllium seed husks, pectin, tara gum and quillaia.

[0034] Natural gums obtained by bacterial fermentation and used in the present invention include gellan gum and xanthan gum.

[0035] According to a particular embodiment, the at least one gum used in the products of the invention is chosen from pectin, guar gum, locust bean gum, tara gum, xanthan gum, Arabic gum, quillaia gum and agar and any mixtures thereof.

[0036] According to another embodiment, the at least one gum consists of a mixture of locust bean gum and guar gum.

[0037] The present invention does not make use of non-natural additive emulsifiers known in the art, such as mono- and diglycerides of fatty acids, acid esters of mono- and diglycerides of fatty acids, sucrose esters of fatty acids, polygylcerol esters of fatty acids, polyglycerol polyricinoleate and polysorbate.

[0038] The acidifier used according to the invention can be an acidic fruit juice, an acidic fruit puree, citric acid, brown sugar, molasses, dried sugar can extract, lactic acid, malic acid or ascorbic acid. The preferred acidifier is a lemon juice concentrate.

[0039] The pH of the frozen confectionary product is comprised between 5.6 and 6.5, when measured at room temperature (25°C).

[0040] In a further aspect a method for the manufacture of the frozen confectionary product is described.

[0041] In a first step of the method, frozen confectionary ingredients 3% to 12%, preferably 4% to 12%, most preferably 4.4% to 10% fat, 2% to 2.7% protein, most preferably 2.4% to 2.7% protein, 0% to 29%, preferably 0% to 26%, most preferably 12% to 26% sugars are blended together with a stabiliser composition comprising egg yolk, optionally one acidifier and at least one natural gum to form a mix.

[0042] Following formation of the mix, a pasteurisation step and an homogenisation step are carried out on the mix. It is not important in which order the pasteurisation step and the homogenisation step are carried out.

[0043] The pasteurisation step is carried out under standard pasteurisation conditions as known in the art. Homogenisation is preferably carried out under standard conditions, as known in the art, adapting to the fat in the formula, namely at a pressure of between 40 and 250 bars, preferably between 80 and 245 bars, more preferably between 100 and 240 bars.

[0044] The homogenised mix may then be cooled to around 2 to 8°C by known means. The mix may further be aged for 4 to 72h at around 2 to 6°C with or without stirring. Optionally, the addition of flavourings, colourings, sauces, inclusions etc. may be carried out prior to the ageing step or during the freezing step. If flavourings, colourings, sauces, inclusions etc. are added, these are preferably selected from natural ingredients only.

[0045] In the next step, the mix is aerated. In a preferred embodiment, the mix may be cooled to a temperature below - 3°C, preferably between -3 and -10°C, preferably at about - 4.5 to -8°C with stirring and injection of gas to create the desired overrun.

[0046] The frozen confectionery is aerated to an overrun of at least 80%, preferably between 80% to 210%, more preferably between 90% to 160%, most preferably between 100% to 150%.

[0047] The aerated mix can be subjected to freezing either by using conventional freezing equipment or by a low temperature extrusion system. In this equipment, the aerated mix is cooled by extrusion at a temperature of below -11°C, preferably between -12°C and -18°C in a screw extruder. The screw extruder may be such as that described in WO temperature extrusion system. In this equipment, the aerated mix is cooled by extrusion at a temperature of below -11°C, preferably between -12°C and -18°C in a screw extruder. The screw extruder may be such as that described in WO 2005/070225. The extrusion may be performed in a single or twin screw extruder.

[0048] The frozen mix is then packaged and stored at temperatures below -20°C, where it will undergo hardening step during storage. Alternatively, it can be hardened by accelerated hardening step, for example via a hardening tunnel, carried out at a temperature between -20°C to -40°C for a sufficient time to harden the product.

[0049] The present invention is illustrated herein by reference to the following examples.

Examples

Tests:

[0050] Melting tests were carried on frozen confectionary products. The percentage of melted ice cream was measured according to the following formula:

[0051] In which, m1 is the mass of the frozen confectionary product with its package in grams; m2 is the mass of the package alone in grams, m3 is the mass of the container alone in grams and m4 is the mass of the container with the dripped product at a given time in grams.

Heat shock test:

[0052] Heat shock stresses were applied to samples over 7 days and each heat shock cycle lasted for 24 hours with temperature variations of between -20 °C to -8 °C.

[0053] The products of the invention are compared in the following example to what is referred to as "standard ice cream" and which is made with additive emulsifiers.

[0054] Best quality standard ice cream made with additive emulsifiers (eg: E471) typically shows less than 40% melting after 180 minutes at 22°C.

[0055] After heat shock stress, best quality standard ice cream made with additive emulsifiers (eg: E471) typically shows less than 60% melting after 180 minutes.

Example 1

[0056] Frozen confectionary products (22 samples) of the following composition were manufactured:

Ingredients	wt% in the end product
Fat (coconut and palm)	4.5% - 12%
Protein (milk and whey)	2.4% - 2.7%
Sugars	12% - 26%
Total solids	36% - 40%

Emulsifier composition:
Egg yolk (powder)	0.8% - 1.5%
Natural gum	0.3% to 0.63%
Acidifier (lemon juice)	0% - 0.15%

[0057] The frozen confectionary products had a pH of between 5.9 and 6.5 and an overrun of between 100 to 120%.

[0058] Surprisingly, none of the samples product shrank during standard heat shock tests, indicating a good stability. The drip test results showed only 20% to 50% melted weight after 180 minutes at 22 °C. The majority of the samples with 20% to 40% melted weight indicated a very good melting profile, similar to a best quality ice cream made with efficient additive emulsifiers.
Sensory evaluation was conducted with an expert sensory panel who did not detect major differences on key texture attributes between the ice creams according to the present invention compared to similar control samples made with additive emulsifiers.
Penetrometry tests results showed that these samples had similar hardness to standard ice cream.

Example 2 (not part of the invention)

[0059] Three frozen confectionary products with different amounts of acidifier with the following composition were manufactured:

Ingredients	wt% in the end product
Fat (dairy fat)	10-11%
Protein (milk and whey)	2.7%-3.1%
Sugars	20-22%
Total solids	36-40%
Egg yolk	0.8-1.5%
Natural gum (guar & LBG)	0.18-0.3 %
Acidifier (lemon juice concentrate 6.8)	0-0.15 %

[0060] The frozen confectioneries could be easily frozen with more than 100% overrun on a standard continuous ice cream freezer.
All samples had good melting resistance with less than 45% melting after 180 min at 22 °C.
All 3 frozen confectionery samples had similar penetrometry to standard ice cream.
None of the samples shrank.
